Book Description
Diatoms are the most species rich group of algae, and they contribute about 20% of annual global carbon fixation. They play major roles in ocean food webs and global biogeochemical cycles. They are also a target of the biotechnology industry because of their nano-patterned silica cell wall and high lipid content. Diatoms have received increasing attention as more genomes became available and because of the development of genome editing tools such as the CRISPR/Cas9 technology, which has made diatoms as genetically tractable as well-established biological model species. This book provides an overview on diatom molecular biology. It brings together international leading experts in the field to discuss the latest data and developments from genes to ecosystems. As the understanding of diatoms is currently experiencing a step change, it is critical to allow for synergistic approaches on diverse aspects of diatom biology and evolution. The books offers fundamental insights into the molecular life of diatoms; at the same time new scientific concepts are developed based on the application of the latest molecular tools and genomic information to explore the fascinating lifestyle of diatoms.

Book Description
This comprehensive guide is designed for researchers, professionals, and students looking to deepen their knowledge of diatoms, including detailed information on diatom photosynthesis regulation at the molecular scale, as well as their significant ecological roles, all aimed at promoting sustainable advancements and the safeguarding of aquatic ecosystems. Diatoms exert an immense influence on the ecosystem of Earth due to their remarkable abundance and species diversity. Thriving in diverse habitats spanning the oceans, intertidal benthic zones, saline and freshwater environments, and even terrestrial niches like moist soil, forests, and caves, they play an integral role. Diatoms alone account for around 20% of the oxygen generated by photosynthesis, comparable to the combined productivity of tropical rainforests worldwide, while their primary production can reach 40–45% in marine ecosystems. Nevertheless, in contrast to the extensive research on macroscopic photosynthetic organisms, investigations in this domain remain comparatively limited, despite the role of diatoms in global biogeochemical processes. This book presents an exhaustive review of the subject matter, encompassing a wide spectrum of topics ranging from the intricate molecular mechanisms of diatom photosynthesis and light absorption to the dominant role of diatoms as primary producers within ecological frameworks. Beyond this, the book delves into the practical implications stemming from diatoms and their photosynthetic productivity. A strong emphasis is placed on the importance of fundamental research in deepening our understanding of the natural world around us. Diatoms Photosynthesis provides readers with a comprehensive guide to understanding the fundamentals of diatom photosynthesis and their ecological significance in aquatic ecosystems; a guide to the potential of diatom-derived products for sustainable technologies; a roadmap from diatom photosynthesis to implications in applied sciences; a bridge to span the gap between fundamental research on diatoms and their practical applications. Audience This book caters to academic professionals, students, and researchers in the fields of marine biology, ecology, microbiology, and biochemistry. It offers insights and benefits into diatom photosynthesis, diatom physiology, biodiversity, ecosystem health, and sustainable technological advancements.

Book Description
High-resolution images of phytoplankton cells such as diatoms or desmids, which are useful for monitoring water quality, can now be provided by digital microscopes, facilitating the automated analysis and identification of specimens. Conventional approaches are based on optical microscopy; however, manual image analysis is impractical due to the huge diversity of this group of microalgae and its great morphological plasticity. As such, there is a need for automated recognition techniques for diagnostic tools (e.g. environmental monitoring networks, early warning systems) to improve the management of water resources and decision-making processes. Describing the entire workflow of a bioindicator system, from capture, analysis and identification to the determination of quality indices, this book provides insights into the current state-of-the-art in automatic identification systems in microscopy.

Book Description
An organism's life cycle is the direct result of its evolutionary history and represents a fundamental aspect of its ancestry and ecology. Yet the process of linking alternating life-history stages has proven to be challenging, if not impossible in some cases. Diatoms (Bacillariophyceae) are no exception to this challenge, and their diversity of life stages and reproductive strategies add further challenges. A central focus of diatom research has been to unravel the evolutionary events that led to their extraordinary diversity, a line of inquiry that has been greatly aided by the availability of next-generation sequence data. Yet without proper taxonomic sampling, many fundamental questions have remained unresolved. Furthermore, the incorporation of data from outgroup lineages provides crucial insights into the ancestral state of a taxon. However the life cycle of the sister lineage to diatoms, the Bolidophytes, has also remained an enigma. Here, to address yet unresolved questions about the origin of the diatom life cycle, transcriptomes for Bolidomonas pacifica (Bolidophyceae) and two diploid diatoms, Leptocylindrus danicus and Hemiaulus sinensis (Bacillariophyceae) were sequenced and analyzed. A novel approach of quantifying the degree of heterozygosity across the genome was used to infer the ploidy in Bolidomonas, whose ploidy level is unknown. Lack of heterozygous alleles in Bolidomonas strongly suggests that it is a vegetatively haploid organism, and the presence of several meiosis-specific genes indicate that it is likely capable of sexual reproduction as well. These results suggest that Bolidomonas represents the haploid phase of a haplodiplonitic life cycle, in which silicified Parmaleans are the diploid phase.

Book Description
Among cell biologists, diatoms are best known for their extraordinary and beautifully nano-patterned cell walls, made of hydrated silicon dioxide—that is, glass. Many of us first encountered diatoms in the form of isolated silica cell walls, known as frustules, mounted on slides used as a measure of resolving power, for dark field alignment of microscopes, or in scanning electron micrographs invoking alien-like architecture. Their exquisite complexity is reminiscent of high-magnification images of snowflakes; however, the diatom frustules are created by genetically encoded developmental programs, and as such are highly reproducible and characteristic for many of the 10,000 to 100,000 estimated species. How do these cells design and build their glass houses? Why do we know so little about the cell biological mechanisms of these exquisite organisms? Classical biochemical methods have identified several important classes of silica-interacting peptides that are tightly associated within biosilica. However, advanced genetic methods have only recently been developed for diatoms, and remain largely inefficient, limiting their use in genome-wide screens. Nevertheless, critical genetic techniques have rapidly improved for key model diatoms in recent years. Improvements to the efficiency of genetic techniques will be key toward our understanding of these mysterious organisms. This work presents molecular genetic data regarding genes and mechanisms by which diatoms control cell shape and metabolism.
